ITIN for Non-Residents 2026: Form 1040-NR and Tax Treaty Benefits Guide
The US maintains tax treaties with 67+ countries, and non-resident aliens need an ITIN for non-residents to claim these benefits. Without an ITIN, the IRS applies 30% default withholding on all US-sourced income under IRC 1441. An ITIN lets you file Form 1040-NR, deduct business expenses, and reduce withholding to 0-15% depending on your country's treaty. itin.so processes applications for $297 (standard) or $297 (express), with IRS approval in 6 to 11 weeks.

Who Counts as a Non-Resident Alien for ITIN Purposes?
The IRS classifies you as a non-resident alien (NRA) under IRC 7701(b) if you are not a US citizen and do not meet the green card test or the substantial presence test. The substantial presence test counts physical presence: 31+ days in the current year AND 183+ days using the weighted 3-year formula.
Common Non-Residents Who Need ITINs
- Foreign nationals owning US rental property (FIRPTA, Section 871(d))
- International freelancers and contractors working for US clients
- Amazon sellers and e-commerce operators on US platforms
- Foreign investors receiving dividends or interest from US sources
- Non-resident spouses filing jointly with US citizen spouses
- International students with taxable income
The Substantial Presence Test Formula
Days in current year + (1/3 of prior year days) + (1/6 of second prior year days). If the total is 183+ AND you were in the US 31+ days this year, the IRS considers you a resident alien. Below 183 = non-resident alien status, requiring Form 1040-NR filing with your ITIN.
What Types of US Income Require an ITIN for Non-Residents?
2 categories of taxable income for NRAs, each with different tax treatment:
Effectively Connected Income (ECI)
Income from a US trade or business: Amazon sales, freelance work, LLC operations, and rental property (with Section 871(d) election). Taxed at graduated rates (10% to 37%) with full business expense deductions allowed. This is the most common income type for Amazon sellers and freelancers.
FDAP Income (Fixed, Determinable, Annual, Periodic)
Passive income: dividends, interest, rents (without 871(d) election), royalties. Taxed at a flat 30% or reduced treaty rate. No deductions allowed. The withholding agent (bank, broker, tenant) collects tax before paying you.
Real Property Income
US real estate rental income can be treated as ECI under Section 871(d), allowing deductions for mortgage interest, property taxes, insurance, repairs, and depreciation over 27.5 years. Without this election, gross rent faces 30% flat withholding. See our real estate investor ITIN guide.
How Do Tax Treaties Reduce Withholding for Non-Residents?
The US has income tax treaties with 67+ countries. These treaties reduce or eliminate the 30% default withholding rate on specific income types. You need an ITIN to claim treaty benefits on Form 1040-NR with Form 8833.
| Country | Business Income Rate | Dividend Rate | Interest Rate |
|---|---|---|---|
| United Kingdom | 0% | 15% | 0% |
| Canada | 0% | 15% | 10% |
| India | 0% | 25% | 15% |
| Germany | 0% | 15% | 0% |
| China | 0% | 10% | 10% |
| No Treaty | 30% | 30% | 30% |
What Are the Tax Obligations for Non-Resident Aliens?
4 obligations for NRAs with US income:
- File Form 1040-NR annually. Report all US-sourced income, claim deductions and treaty benefits, calculate actual tax liability. Deadline: June 15 (automatic extension for NRAs with no US wages), extendable to October 15 via Form 4868.
- Submit W-8BEN to withholding agents. Every US entity paying you needs a W-8BEN on file to apply the correct withholding rate. Your ITIN goes on Line 5.
- Maintain your ITIN. ITINs expire after 3 consecutive years of non-use per the PATH Act of 2015. File regularly to keep it active. See our ITIN expiration guide and renewal guide.
- Report foreign-owned LLCs. If you own a US LLC, file Form 5472 + pro forma Form 1120 per IRC 6038A. $25,000 penalty per year for non-filing. See ITIN for LLC owners.
